Azure Serverless Computing Cookbook - Third Edition

By: Praveen Kumar Sreeram

Overview of this book

This third edition of Azure Serverless Computing Cookbook guides you through the development of a basic back-end web API that performs simple operations, helping you understand how to persist data in Azure Storage services. You'll cover the integration of Azure Functions with other cloud services, such as notifications (SendGrid and Twilio), Cognitive Services (computer vision), and Logic Apps, to build simple workflow-based applications. With the help of this book, you'll be able to leverage Visual Studio tools to develop, build, test, and deploy Azure functions quickly. It also covers a variety of tools and methods for testing the functionality of Azure functions locally in the developer's workstation and in the cloud environment. Once you're familiar with the core features, you'll explore advanced concepts such as durable functions, starting with a "hello world" example, and learn about the scalable bulk upload use case, which uses durable function patterns, function chaining, and fan-out/fan-in. By the end of this Azure book, you'll have gained the knowledge and practical experience needed to be able to create and deploy Azure applications on serverless architectures efficiently.

Testing Azure functions

The Azure Functions runtime allows us to create and integrate many Azure services. At the time of writing, there are more than 20 types of Azure function that you can create. This recipe will explain how to test the most common Azure functions; we'll look at the following:

  • Testing HTTP triggers using Postman
  • Testing a blob trigger using Azure Storage Explorer
  • Testing a queue trigger using the Azure portal

Getting ready

Install the following tools if you haven't already done so:

  • Postman: This is a tool that will allow you to make calls to APIs. You can download this from https://www.getpostman.com/.
  • Azure Storage Explorer: You can use Storage Explorer to connect to your storage accounts and view all the data available from different storage services, such as blobs, queues, tables, and files. You can also create, update, and delete them directly from Storage Explorer. You can download this from http://storageexplorer...
